We saved $4500 today! That's enough to buy one of those bottles of pills that Tom takes (that we get for only $35). We were told by one a/c company that we needed to purchase two new a/c units. A second company found the source of one a/c problem and repaired it but confirmed that we do, in fact, need to replace the other, older unit.
That news put a BIG smile on Tom's face. Whew.
I'll retire the a/c subject now. Thanks for listening.
